Transversals & Angles

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

Define corresponding angles.

Back

Corresponding angles are pairs of angles that are in the same position on different parallel lines cut by a transversal. They are equal.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines on opposite sides of a transversal. They are equal.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines on opposite sides of a transversal. They are equal.

Front

What is the relationship between supplementary angles?

Back

Supplementary angles are two angles whose sum is 180 degrees.

Front

What is the relationship between complementary angles?

Back

Complementary angles are two angles whose sum is 90 degrees.

Front

If Angle 1 and Angle 5 are corresponding angles, what can be said about their measures?

Back

Angle 1 and Angle 5 are equal in measure.

Front

If Angle 2 and Angle 6 are corresponding angles, what can be said about their measures?

Back

Angle 2 and Angle 6 are equal in measure.

Front

What is the sum of the measures of vertical angles?

Back

Vertical angles are equal, so their measures are the same.

Front

If two parallel lines are cut by a transversal, what can be said about the alternate interior angles?

Back

The alternate interior angles are equal.
